Fully Automatic sandwich panel production line
this machine is designed for manufacturing different types of the sandwich panels in automatic mode. We used one/two-component PUR adhesive technology to create a technological process for gluing different materials such as PVC, HPL, steel, plasterboards, OSB with insulated foamed boards of EPS, XPS, PUR, PIR, wood wool boards, etc. Because some of the bonding materials cannot be heated up to make a curing process faster, and only cold pressing technology could be used, we had chosen 2-C PUR with 3 minutes Open Time and Press Time.
Fully Automatic Two Components Pu Glue Spraying Machine(also called ab glue dispensing machine) for Spc Honeycomb Panel.

The glue Spraying line is based on the reform of the traditional roller glue coating machine,can be widely used in all kinds of honeycomb panel lamination,such as aluminium honeycomb panel,SPC honeycomb panel,HPL honeycomb panel,marble stone honeycomb panel,stainless steel cabinet panel,fire retardent door,rock wool panel and sandwich panels etc.
The basic functions of this equipment are:

1.Automatic edge finding: (automatic recognition) automatically adjusts the glue spraying position according to the size and length of the board;
2. Automatic glue amount: (automatically adjusts the speed of glue dispensing according to the size of the board and the conveying speed);
3. Automatic glue feeding: When the glue volume in the glue barrel is lower than the set lower limit, the glue adding process will be automatically started.
4. One-click start: Eliminate the tedious preparation work before starting up, and realize automatic operation to working status with one click;
5. Glue heating: The equipment is equipped with glue heating and heat preservation functions, so that the glue is not restricted by ambient temperature and region, allowing customers to choose the brand of glue more freely;
6. Anti-sedimentation mixing: A glue barrel is equipped with an intelligent control mixing device to prevent precipitation or stratification caused by long-term stasis of glue, and to ensure that the glue is heated evenly.

7. Visual mixing: The equipment adopts imported dynamic mixing tubes and is matched with Taiwan's high-speed brushless motor to achieve adjustable mixing speed and direct viewing of the mixing status to ensure uniform mixing;
8.Disassembly-free automatic cleaning: The equipment adopts a high-pressure gas-liquid automatic switching cleaning device. There is no need to disassemble the glue spray head, achieving true disassembly-free cleaning in the industry, and the cleaning effect is visible to the naked eye;
9.Patented glue-controlled suction valve: The equipment is equipped with our company's patented glue-controlled anti-drip suction valve, which can open the glue in time and close the glue quickly with suction adjustment;
10.Special metering pump: The equipment adopts a special polyurethane high-flow and wear-resistant precision metering pump , which can accurately control glue and adjust the flow rate to achieve an accuracy of ±0.5%, effectively avoiding inaccurate proportions and greatly improving the product qualification rate;
